Summary: Magnetic fluid has a significant impact on displacement efficiency in porous media under the influence of magnetic force. Through experimental and numerical simulation studies, we have obtained the relationship curves between displacement efficiency and controllable variables, and demonstrated the distribution and force field of the mixed fluid during the displacement process. The findings are important for further understanding and application of externally field-assisted oil displacement processes, as well as in the fields of microfluidics, pollutant diffusion, microsensors, etc.

Summary: Mitigating errors is a significant challenge for near-term quantum computers. This paper proposes a complementary scheme to actively reduce readout errors by encoding single qubits into multiqubit states prior to readout. The scheme's computational resources are independent of circuit depth and compatible with current device error rates and connectivity. As a proof of principle, an 80% improvement in readout error is demonstrated on the IBMQ Mumbai quantum computer.

Summary: This study numerically simulates the time-based unsteady flow of Casson-Williamson nanofluid over a magnetic dipole enabled curved stretching sheet, considering factors such as thermal radiation, Joule heating, an exponential heat source, homo-heterogenic reactions, slip, and melting heat peripheral conditions. The analysis shows that the thermal buoyancy component enhances the velocity regime, while the melting parameter and radiation parameter have counterintuitive effects on the thermal profile. The ferrohydrodynamic interaction parameter slows down the velocity distribution of the nanofluid flow. Graphical representations of streamlines and isotherms are provided to demonstrate the flow and heat distribution.

Summary: With the development of Lab on a chip technology, fluid management using dispersed droplets has become an important approach. Electrowetting on dielectric (EWOD) is one method for droplet actuation, but it requires prior definition of droplet positions. Optoelectrowetting (OEW) goes further by allowing changes in electrical parameters through impinging light spots, without the need for predefined droplet positions. This study re-evaluates the key parameters of OEW and explores their effects on droplet actuation using numerical optimization methods.
